Hi,
I saw you need an electronic engineer for your project. But firmware is special, and the success of your project depends on having solid knowledge in electricity and communications - so there's a lot at stake in getting this right and imagine you're looking for someone who 'gets' how important this is to you.
I develop firmware for microcontrollers like STM32(and other ARM Cortex M), ESP32, ESP8266, and SoM(systems on modules) like Raspberry Pi in C/C++(FreeRTOS), Python, and MicroPython, but I approach it a little bit differently than most. Since my job is to help you by producing professional designs that not only look great but also implement a design strategy that makes it easier to integrate your prototype with other technologies like cloud computing, data analytics, machine learning, etc. For instance, I designed a device for monitoring and tracking system for wild alpacas with a temperature and heart rate sensor, also a GPS module, you can check it on my portfolio. I am very interested in your project, and with the immediate availability to focus on it.
Here's what my first client said about me: "Luis has done a very good job. He has been supportive and keen to note the requirements and deliver on time with good quality"
P.S. Shot me a message with timeslots you're available, and I can run you through it on a call together
